for a - CHO aldehyde group we use secondary prefix as formyl,oxo,aldo and secondary sufix as al
for -CO- ketone group we use secondary prefix as Oxo and secondary suffix as one.
yahh one thing more
in case of - CHO , two diffrent prefixes are used Aldo or formyl and oxo. secondary priffix formul or aldo is used when - CHO is directly attached to main chain but seconadry prefix Oxo is used in case when alkyl group is attached to main skelton .
also secondary preffix oxo is used for aldehyde as well as keetons when CO is part of main or side skelton and the carbon of CO is counted in skelton.
hope this will help you
good luck
